Dear Colleagues,
Our next Mathematical Colloquium will take place on Sunday, November 13, at
Speaker:     Prof. Michael Cwikel
Affiliation: Technion, Haifa, Israel
Title:       A simple(?) geometric question with deep consequences for BMO
Date:        Sunday, November 13, 2011
Time:        11:30
Venue:       Seminar Room 426/8, Science Building
I will pose and invite you to solve a seemingly rather simple
geometric/combinatoric question. My coauthors and I have discovered that an
affirmative answer to this question would have some very interesting
consequences in analysis. They relate to the very important function space
BMO (of functions of Bounded Mean Oscillation). I will briefly describe BMO,
and mention some of its remarkable properties and connections with harmonic
analysis and complex analysis. Special cases of one of our results give
alternative proofs of the celebrated John-Nirenberg inequality for BMO
functions. An affirmative answer to the above-mentioned question would lead
to a version of the John-Nirenberg inequality with dimension free constants.
A more extensive version of this abstract and a first version of our
detailed paper etc. are available at
This is joint work with Yoram Sagher and Pavel Shvartsman.
Light refreshments will be served at 11:15 am. Everybody is welcome.
Looking forward to seeing you all,
